Do you have a calculator?
1) To find the product of 35.72 and 0.00590, you simply multiply these two numbers together. The product is calculated as follows:
35.72 x 0.00590 = 210.9828
So, the answer is 210.9828.
2) To divide 0.4832 by 5.12, you can use the division operator (/). The division is calculated as follows:
0.4832 / 5.12 = 0.094375
So, the answer is 0.094375.
3) To multiply (6.09 x 10^-1) and (9.08 x 10^5), you need to multiply the numbers together, and then multiply the exponents together. The multiplication is calculated as follows:
6.09 x 10^-1 = 0.609
9.08 x 10^5 = 9080000
Multiplying these two numbers gives:
0.609 * 9080000 = 5,527,272
So, the answer is 5,527,272.
4) To divide (7.79 x 10^4)(4.56 x 10^3) by (2.93 x 10^3)(3.2 x 10^2), you can divide the numbers and then divide the exponents. The calculation is done as follows:
(7.79 x 10^4)(4.56 x 10^3) = 3.54824 x 10^8
(2.93 x 10^3)(3.2 x 10^2) = 9.376 x 10^5
Dividing these two numbers gives:
(3.54824 x 10^8) / (9.376 x 10^5) = 378.8467
So, the answer is 378.8467.
5) To add (2.3 x 10^2) and (7.16 x 10^5), you need to align the exponents and then add the numbers. The addition is calculated as follows:
(2.3 x 10^2) + (7.16 x 10^5) = (0.23 x 10^3) + (7.16 x 10^5) = 0.23 x 10^3 + 716 x 10^3 = 716.23 x 10^3
So, the answer is 716.23 x 10^3.
